encryption - Use preexisting RSA SSH keys to decrypt a text in C# -


i have pair of rsa public/private keys generated 'ssh-keygen' command in linux computer. there ruby application in linux computer encrypts string using public key, , want use private key decrypt string in windows c#/.net application. took @ bouncy castle libs, without success. example or tip helpful. thanks!

is there reason use ssh keys?

any rsa key suffice. need extract rsa key encrypt anything. , if key not rsa, cannot encrypt anything, dsa signature algorithm. there rfc public keys: http://www.ietf.org/rfc/rfc4716.txt not need. may understand how extract each part. should base64 encoded binary chunks.

you can try putty source http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html keygen can generate , convert keys. so, if find place extracts rsa key. use crypto library compute rsa using keys , data. correct keys, input data + padding. depends whether public or private key used ruby program. hope helps.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
